You belong to me ~Carla Bruni

See the Pyramids
Along the Nile
Watch the sun rise
On a tropic isle
Just remember darling
All the while
You belong to me

See the market place
In old Algiers
Send me photographs
And souvenirs
Just remember
'Til your dream appears
You belong to me

I'll be so alone
Without you
Maybe
You'll be lonesome too
And blue

Fly the ocean
In a silver plane
See the jungle
When its wet with rains
Just remember
Till you're home again
You belong to me

"The Nake Man"

It's so funny for this drama "how i met your mother" ╮( ̄▽ ̄")╭
By the sum of his parts,he is just a man.But by what he does with those parts,he becomes so much more.He may not fit society's definition of a hero,but he is the hero I needed.The hero who helped me recover from the disaster of my failed almost-marriage and get back into the game.He lives in the shadows. Is he a dream?Truth? Fiction? Damnation? Salvation?He is all these things and none of them.For he is...

When I felt depressed , I would listen this song. It made me relaxed.


How do you make Platinum Iridium STM tips

Platinum Iridium (Pt-Ir) is preferred for use in air because platinum does not easily oxidize. The tiny fraction of Iridium in the alloy makes it much harder. A tip made with pure platinum would naturally become blunt in a short time, as the atoms on the end of the tip would flow around to minimize the surface.

The Pt-Ir tips are usually shaped by cutting Pt-Ir wire with a wire cutter. The standard technique uses a wire cutter (diagonal cutters) and a pair of pliers. Grab the wire with the pliers hold the cutters at an acute angle to the wire and as you start to cut into the wire pull with the pliers. Ideally as you start cutting through the wire it will weaken and break at the end of the point. The idea here is that because the wire broke apart the tip was never touched by the cutters, avoiding possible contamination of the tip.

You don't have to use Pt Ir wire. I have also made tips with copper wire that have achieved "atomic" resolution on graphite, and independently others have done the same on commercial machines. Copper tips don't last as long and at higher bias voltages they can quickly oxidize in the surface water contamination. It is not the best for the long term but it is cheep and easy.

Tungsten wire is often used for STM tips. Tungsten (W) is very hard and it is easy to electro-chemically etch to a fine point. One drawback Tungsten slowly oxidizes in air. Tungsten can be electro-chemically etched in KOH or NaOH solutions. I have attempted to use a drain cleaner that is mostly NaOH to electro-chemically etch tips but with only marginal success.

all the world(I tell myself)

when I's broken up , I's so sad.I had many chioces.I could swallow my anger, or throw it in someone's face.There's a third option.I could just let it go,and only when you did that's it really gone,and I could move forward.SO.........I should keep going :).



Lyrics
Say that I'm changed
Say I'm different
Maybe I finally understand
Say I've let go
Say that it's obvious
I tell myself over and over
And over and over again

I'm ready I'm ready
I'm ready to believe

Tell me I'm strong
Tell me I'm weak
Tell me I'll never, never bend
Tell me I'm fire
Tell me I'm cold
Cold I tell myself over and
Over and over again

I'm ready I'm ready
I'm ready to believe

'Cuz I want to feel my heart
Yes I want to feel my heart
Yeah I want to feel feel feel my heart

So tell me I'm strong
Tell me I'm weak
Tell me I'll never understand
Oh, but I'm ready
I'm ready I'm ready to believe
